Spark Platform

Spark Webhooks

Outbound webhook delivery from the Spark platform. When a Property, Member or Office record changes in an upstream MLS, Spark POSTs a RESO Web API Entity Event payload over HTTPS to a subscriber URL, signed with an HMAC-SHA256 signature in a Signature header, with up to 3 retries, exponential backoff and a roughly 2-second response timeout. Subscriptions are filtered by MLS and resource type and support catch-up replay. FBS holds a RESO webhooks 1.0.0 certification endorsement for this surface. Subscriptions are arranged with FBS rather than self-provisioned.
